PCI: sysfs: Revert "rescan" file renames
We changed these sysfs filenames:
.../pci_bus/<domain:bus>/rescan -> .../pci_bus/<domain:bus>/bus_rescan
.../<domain:bus:dev.fn>/rescan -> .../<domain:bus:dev.fn>/dev_rescan
and Ruslan reported [1] that this broke a userspace application.
Revert these name changes so both files are named "rescan" again.
Note that we have to use __ATTR() to assign custom C symbols, i.e.,
"struct device_attribute <symbol>".

[bhelgaas: commit log, use __ATTR() both places so we don't have to rename
the attributes]
Fixes: 8bdfa145f582 ("PCI: sysfs: Define device attributes with DEVICE_ATTR*()")
Fixes: 4e2b79436e4f ("PCI: sysfs: Change DEVICE_ATTR() to DEVICE_ATTR_WO()")
